Latest Patents

Dullea holds a patent for a method titled "Laser tuning of ceramic bandpass filter." This invention involves a laser tuning method that includes forming an untuned filter with at least one metallized element, such as a resonator pad made from an undersized metal plate. A thick film of metal powder paste is applied adjacent to the undersized plate. The paste film is then scanned with a laser beam to sinter the metal particles into an integral plate, allowing for adjustments in size and shape to achieve desired performance characteristics. The process includes monitoring an output signal in response to a test signal while laser scanning the paste film, discontinuing the laser beam once the desired characteristic is obtained. Dullea's innovative work in this area has resulted in 1 patent.
